The official currency is the West African CFA Franc (XOF), divided into 100 centimes. The CFA Franc is linked to the Euro at a fixed rate of exchange. New notes were issued in 2004 and only those issued by the Bank of West African States (Banque des États de l'Afrique de l'Ouest) are valid currency. There are a few ATMs in Abidjan but most will accept only Visa cards. It is unwise to use an ATM that is not guarded. Credit cards are accepted in the larger hotels and more established restaurants. Most shops require cash.
